10. Multifunction Timer Pulse Unit (MTU)
Waveform Output Operation (0 Output/1 Output): Figure 10.10 shows 0 output/1 output. In
the example, TCNT is a free-running counter, 1 is output upon compare-match A and 0 is output
upon compare-match B. When the pin level matches the set level, the pin level does not change.

Waveform Output Operation (Toggle Output): Figure 10.11 shows the toggle output. In the
example, the TCNT operates as a periodic counter cleared by compare-match B, with toggle
output at both compare-match A and compare-match B.
